Ideal for heavy-duty applications

MAXXDRIVE® industrial gear units

For applications up to 250 kNm, NORD DRIVESYSTEMS provides robust industrial gear units that are characterised by very high power density, quiet operation and top reliability. The modular system with its multiple options ensures an extremely high level of design flexibility.

M‌AXXDRIVE® industrial gear units from NORD DRIVESYSTEMS provide high output torques from 15 to 250 kNm and are ideal for use in heavy-duty applications such as agitators, belt drives, mixers, mills, drums or crushers. Thanks to the torsionally rigid one-piece UNICASE housing they achieve a longer bearing life than gear casings manufactured from jointed parts and ensure efficient power transmission and high tolerance for peak loads and impacts. Large low-friction rolling bearings ensure extremely high axial and radial load capacities and a long service life. High-precision axis alignment ensures quiet running. NORD industrial gear units are offered as parallel gear units or as right-angle gear units and cover speed ratios from 5.54:1 to 400:1, as well as up to 30 000:1 with an auxiliary primary stage gear unit. Mounting and fastening can take place on all six sides of the gear unit.

 

MAXXDRIVE® XT for applications with high thermal limit powers

NORD has developed its MAXXDRIVE® XT series 2-stage right-angle gear units especially for applications where low speed ratios in combination with high power performance is required. As standard, the series is equipped with a heavily ribbed UNICASE housing and an integrated axial fan. Due to the increased surface and the air guide covers, the cooling air flow is optimised and a very high thermal limiting power is achieved. In many cases, additional cooling is not required. Large roller bearings and centre distances increase the load capacity and service life of the components.

 

Economical modular system

Based on the modular system, NORD plans complete and customised drive systems for heavy-duty operation. This way, attractive solutions can also be provided for price-sensitive industries. This is based on a comprehensive range of frequency inverters, motors, gear units and attached components like couplings, brakes, swing frames and many other options. For example, various versions of drive and driven shafts, mountings, sealing systems, back stops, auxiliary gear units, cooling equipment and sensors for condition monitoring (speed, temperature, vibrations, etc.) are available. For each application, respective features such as hydraulic couplings tailored to the particular process and gear unit, or Taconite seals that effectively protect shaft sealing rings against abrasive dust and corrosion, ensure smooth operation.
